adapted to be distributed to a burner 13 To 'all whom it may concern:

Be it known that I, Enocn An'rnrun Pmson, a citizen of the United States, and a resident of the city of Chica o, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in an Oil-Burning Mechanism; and I hereby dcclare that the following is a full, clear, and exact descri tion ofthe same, reference being had to t e accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification.

This invention relates to oil burning mechanisms and has for its object the provision of an efiicient oil burning device and one which may be readil removed from the furnace for inspection, caning, renewal or re air.

' ith the above and other objects in view, as will be apparent, this invention consists in the construction, combination and arrangement of arts, all as hereinafter more fully describe claimed and illustrated in the accom an in drawin On the dr wiggsz gs? Fi re 1 is a vertical elevation in section, showing a device embodying this invention.

gigure 2 is a plan view of the same.

Figure 4 is a section along the line 4--4 of Figure 2.

Figure is a detail view of the mechanism for antomaticall cutting off the oil supply.

As shown on t e drawings:

Numeral 1 re resents a fire box of a furnace having a cor 2 communicatin therewith from without said furnace. umeral 3 represents an air chamber in said furnace in which air is adapted to be compressed for combustion with the oil in said furnace. A cast-ing 4 is supported between the furnace proper and said chamber 3. The casting 4 is supported on ate bars 5 resting on bearer bars 6 which are suitably suprted in the boiler. Suitable closing means surrounds the casting 4 on the grate bars 'for restricting the communication between the furnace 1 and the air chamber 3 through apertures 8, 9 and 10 in the casting 4. Bemovably secured on the casting 4 and communicating with the apertures 8 and 10 therein is a manifold 11 having a downwardly disposed aperture 12 therein through which air communicated to said manifold through said apertures 8 and 10 is gure 3 is a section along the line 3-3 p of Figure 2.

supported on the casting 4 beneath said manifold 11. Secured to the upper side of the manifold 11 is a ring bolt 11" adapted to receive the end of a rod or the like for facilitating the removal of said manifold. The burner 13 is of substantially conical shape and has centrally positioned therein a pipe 14 which communicates through a valve 15 to a supply line 16' for supplying oil to the burner. The burner 13 presents substantiall a sphericalsurface immediately surroun ing the. opening, of the pipe 14 therein. Below the spherical surface of the burner are a series of concentric stripped the grooves 17. Thespherical surface 0 burner is ada ted to more evenly distribute the oil ra i 1y over the surface of the burner. e grooves 17 are adapted to retard the oil flowin down side of the burner, insuring com ete combustion thereof. Lugs 18 on the urner are adapted for eng ment beneath the heads of the studs 19 secured in the casting 4. The aperture 9 in the casting 4 is ada ted for communi:

cation between the cham 3 and the bottom of the burner, the burner being shaped I at its lower edge for permitting the air to flow therebeneath from the lower side of the burner to the upper side thereof. An

overflow pipe 20 is secured to the casting 4 and communicates therewith for carrying away any unconsumed oil from the burner. The end 21 of the pi 20 .(Figure 5) is positioned over 'a bu et 22 secured to a suitable valve 23 in vthesupply line 16 for shutting ofi the oilcommumcated therefrom to thevalve 15 when the oil in the bucket 22 reaches a redetermined amount. A valve 24 in the inc is adapted to be opened to admit fuel to the valves 23 and 15. The operation;

Air in the chamber 3 is adapted to enter a manifold 11 through the apertures 8 and 10 and be distributed over the a rture 24' over the upper surface of the urner. Likewise air passes throu h the aperture 9 to the under side of the urner under the lower edges thereof to the oil in the burner; said air unites with the oil insuring the com plete combustion thereof. 7 It is also to be noted that the air in both cases is preheated before uniting with the oil. The oil which is pum to the center of the burner descends y gravity over the spherical surface to the steps 17. In case of too great a supply of oil or if the burner for any reason should go out, the unconsumed oil will flow out through the oil return pipe 20 to the drip' bucket 22 which operates the valve 23 for automatically shutting off the oil and preventing danger of explosion when the furnace is again started up.

Another important feature is the ready removal of the burner. This can be effected by removing the valve by means of unscrewing the union secured thereto, slightly rotating the burner to release the In 18 from underneath the heads of the stu elevating the manifold 11 out of the way and then pulling the burner ortion out through the furnace door 2, u lin the oil inlet pipe 14, outwardly t erea tel and therewith through the aperture 9. It will be seen that the structure arrangement of parts of the mechanism embodying this invention provides a very economical and efficient burner, one which is readily removable for inspection, cleaning, renewal or repair and which is automatically guarded against overflow and danger of" explosion.

I am aware that many changes may be A made, and numerous details of construction may be varied through a wide range without departing from the principles of this invention, and 1 therefore do not purpose limiting the patent anted hereon, other- .wise than necessitate by the prior art.

* I claim as my invention:

1. An oil burner comprising a circular member having a convex cross-section, an integral hemispherical portion in the center of said member, means in said portion for ejectin oil over the surface thereof, and integra concentric stepped grooves on said member joining the lower edge of said hemispherical portion. i

2. The combination with a furnace having van air chamber therein, of a burner situated over said chamber, of an air passage communicating with said chamber and said burner and a pipe connected to said burner for ejecting 'oil over the surface thereof,

a readily accessible connection oommuni-r drawn said burner and-a pipe connectedto said burner for ejecting oil over the surface thereof, a readily accessible connection in said pipe, means on said burner upon a slightrotational movement thereof to release the same from rigid engagement over said member,

the pipe connected thereto being adapted to be drawn outwardly thereafter and there with through said air passages when said readil accessible connection has been remov said connection being accessible from without said furnace.

In testimony whereof I have hereunto subscribed my name.
